    Where We Install

    Patio Door Options

    • Sliding Glass Patio Doors :

      The most popular residential patio door. One or more panels glide horizontally on a track, providing a wide opening without swinging into your living space. Available in 2-panel, 3-panel, and 4-panel configurations with standard and oversized heights.

    • French Patio Doors :

      Hinged double doors that swing inward or outward, offering a classic, elegant entry to your patio, deck, or garden. Glass panels run the full height of the door for maximum light and visibility.

    • Multi-Slide and Pocket Patio Doors :

      Premium systems where multiple glass panels slide and stack — or disappear into a wall pocket — creating a fully open transition between indoor and outdoor living. The ultimate option for entertaining spaces and modern open-concept homes.

    • Single Panel Patio Doors :

      A single hinged glass door for smaller openings. Common in condos, apartments, and secondary exits to side yards or balconies.

    Why Professional Patio Door Installation Matters

    • Weathertight Performance :

      Patio doors are large openings in your home's envelope. Improper installation leads to air infiltration, water intrusion, and energy loss. Professional installation includes proper flashing, drainage planes, and perimeter sealing to prevent leaks.

    • Smooth Operation :

      A patio door that's difficult to open defeats its purpose. We ensure tracks are level, rollers are properly adjusted, and panels glide smoothly. French doors are aligned so both panels close flush with no gaps.

    • Security :

      Patio doors are a common entry point for break-ins. We install multi-point locking hardware, foot bolts, and secondary security bars. Tempered or laminated safety glass comes standard.

    • Energy Efficiency :

      Modern patio doors with Low-E glass, argon gas fill, and thermally broken frames dramatically outperform older single-pane sliding doors. An upgrade can reduce energy loss through that opening by 30–50%.

    • Code Compliance :

      Patio doors must meet local building codes for safety glass, egress, energy rating, and wind resistance. We ensure every installation passes inspection.

    Our Patio Door Installation Process

    Step 1 — Consultation and Measurement

    We assess your existing opening (or plan a new one), discuss door style preferences, and take precise measurements including rough opening, floor levelness, and header height.

    Step 2 — Product Selection

    Based on your space, budget, and aesthetic goals, we recommend the right door system, glass type, frame material, and hardware finish.

    Step 3 — Professional Installation

    Our crew handles removal of the old door (if applicable), rough opening preparation, flashing and waterproofing, door installation, hardware mounting, and final adjustment for smooth operation.

    Step 4 — Inspection and Walkthrough

    We test every function — sliding, locking, sealing — and walk you through operation and maintenance before we leave.

    Patio Door Replacement vs. New Installation

    • Replacing an existing patio door?

      We remove your old door, inspect and repair the rough opening as needed, and install the new door into the existing frame space. Most replacements are completed in 4–6 hours.

    • Adding a new patio door where there isn't one?

      Creating a new opening requires structural assessment (load-bearing wall considerations), framing, header installation, and finishing. We coordinate the full scope — from cutting the opening to installing the finished door.

    Patio Door Installation FAQs

    Standard 2-panel sliding glass patio door installation typically ranges from $1,500–$3,500, including the door and labor. French patio doors range from $2,000–$5,000+. Multi-slide and pocket systems start around $5,000 and can exceed $15,000 for large configurations. We provide free in-home estimates.

    Most replacement installations take 4–6 hours in a single day. New openings (cutting into an existing wall) may take 1–2 days depending on structural work required.

    If your frame and hardware are in good condition, we can often replace just the glass panel rather than the entire door system. This is particularly common for sliding doors with cracked or foggy glass. See our multi pane glass ← link page for insulated glass replacement details.

    Multi-pane glass with Low-E coating and argon gas fill, combined with a thermally broken frame (vinyl or fiberglass), delivers the best energy performance. Triple-pane options are available for extreme climates.
